说明: 它看似一颗上头有撞击坑的太空巨钻。它是小行星龙宫(162173 Ryugu),目前日本游隼二号太空船正往这颗近地小行星靠近。企图心十足的游隼二号,携带了一大群可与母船分离的探测器,包括2部撞击器、4部近距离悬浮器、3部表面跳跃器、与1部移动式小行星表面侦搜器(MASCOT)。这些大部分配有相机的探测器,将降落在龙宫小行星的表面,到处移动并进行探索。除此之外,游隼二号本身将收集表面样品,并在2020年底把样器送回地球进行详细分析。先前我们所知的小行星龙宫,只有它的轨道、宽度大约1公里及它黝黑的表面会反映出不寻常的色泽。研究小行星星龙宫,除了能让人类了解它的表面和内部之外,还可以得知在早期的太阳系,有那些可供生命发展的物质。在上面一系列的逐渐靠近影像里,小行星上头的特徵可能是巨岩撞击坑

Explanation: It looks like a big space diamond -- but with craters.It's 162173 Ryugu (Dragon's Castle), and Japan's robotic Hayabusa2 mission is now arriving at this near-Earth asteroid.Ambitious Hayabusa2 is carrying an armada of separable probes, including two impactors, four small close-proximity hoverers, three small surface hoppers, and the Mobile Asteroid Surface Scout (MASCOT) which will land, study, and move around on Ryugu's surface.Most of these are equipped with cameras. Moreover, Hayabusa2 itself is scheduled to collect surface samples and return these samples to Earth for a detailed analysis near the end of 2020. Previously, what was known about asteroid Ryugu was its orbit, that it spans about one kilometer, and that it has a dark surface that reflects unusual colors. Studying Ryugu could tell humanity not only about Ryugu's surface and interior, but about what materials were available in the early Solar System for the development of life. Pictured, a series of approach images shows features suggestive of large boulders and craters.
